Ted Raicer has just posted a 1942 scenario for Barbarossa to Berlin. There is also a new version of the living rules available which incorporates all the errata - just after I've laboriously copied them into the previous ruleset. And GMT have buried this excellent Expanded Turn Track deep in their site where no-one will ever find it.
I've got this game set up on the table at home now and am driving into Russia in odd moments between meals, coursework, dusting etc. Really impressed so far - this is a worthy successor to Paths of Glory. Maybe this will be my one true game?
